Subject: [PATCH v3 8/9] ARM: dts: Add "syscon" compatible string to chipid node
Date: Tue, 13 Aug 2019 17:08:26 +0200
Message-ID: <20190813150827.31972-9-s.nawrocki@samsung.com> (raw)
In-Reply-To: <20190813150827.31972-1-s.nawrocki@samsung.com>

The CHIP ID block in addition to exact chip revision information
contains data and control registers for ASV (Adaptive Supply Voltage)
and ABB (Adaptive Body Bias). Add "syscon" compatible so the CHIPID
block can be shared by respective drivers.
